Add VecSlot for unboxed sums of SIMD vectors

This patch adds the missing `VecRep` case to `primRepSlot` function and
all the necessary machinery to carry this new `VecSlot` through code
generation. This allows programs involving unboxed sums of SIMD vectors
to be written and compiled.

Fixes #22187

Remove SIMD conversions

This patch makes it so that packing/unpacking SIMD
vectors always uses the right sized types, e.g.
unpacking a Word16X4# will give a tuple of Word16#s.

As a result, we can get rid of the conversion instructions
that were previously required.

Fixes #22296

Cmm Lint: relax SIMD register assignment check

As noted in #22297, SIMD vector registers can be used
to store different kinds of values, e.g. xmm1 can be used
both to store integer and floating point values.
The Cmm type system doesn't properly account for this, so
we weaken the Cmm register assignment lint check to only
compare widths when comparing a vector type with its
allocated vector register.

Scrub various partiality involving lists (again).

Lets us avoid some use of `head` and `tail`, and some panics.

More precise types for fields of OverlappingInstances and UnsafeOverlap in TcSolverReportMsg

It's clear from asserts in `GHC.Tc.Errors` that `overlappingInstances_matches`
and `unsafeOverlapped` are supposed to be non-empty, and `unsafeOverlap_matches`
contains a single instance, but these invariants are immediately lost afterwards
and not encoded in types. This patch enforces the invariants by pattern matching
and makes types more precise, avoiding asserts and partial functions such as `head`.

Add SpliceTypes test for hie files

This test checks that typed splices and quotes get the right type
information when used in hiefiles.

See #21619
